Derek Jeter says he was kidding with infielder Miguel Cairo about getting old when The Post snapped the Yankee captain pointing to his right elbow and grimacing during a workout yesterday at the minor league complex.

“We were just playing around,” Jeter said. “We were saying to each other how old we were.”

Jeter, who will be 32 in June, was asked if his elbow was bothering him.

“No, no, not at all,” said Jeter, who took batting practice and fielded ground balls before the picture was taken and worked with a heavy medicine ball afterward.
